Fit One-way Model
Description
Fits a One-way model to univariate data grouped by a factor, the
result often being displayed using rfs
Usage
oneway(formula, data, location=mean, spread=function(x) sqrt(var(x)))
Arguments
formula |
formula of the form y ~ x where y is the
numeric response and x is the grouping factor
|
data |
data frame in which the model is to be evaluated
|
location |
function or numeric giving the location statistic to
be used for centering the observations, e.g. median , 0 (to
avoid centering).
|
spread |
function or numeric giving the spread statistic to
be used for scaling the observations, e.g. sd , 1 (to
avoid scaling).
|
Value
A list with components
location |
vector of locations for each group.
|
spread |
vector of spreads for each group.
|
fitted.values |
vector of locations for each observation.
|
residuals |
residuals (y - fitted.values ).
|
scaled.residuals |
residuals scaled by spread for their
group
